Concrete surfaces are prepared prior to resurfacing, when upgrading to a decorative finish, and prior to various floor coatings installations in industrial, commercial, and institutional applications.
Proper surface prep is crucial to any successful floor installation. Coatings adhere to concrete at a specific Concrete Surface Profile (CSP), achieved mechanically through grinding, scarifying or shotblasting.
Preparation methods
Scarification & Milling
Efficient removal of trowel-applied epoxy floors; high, uneven or curled concrete joints; elastomeric membranes; and ceramic tile floors.
Diamond Grinding
Heavy-duty grinding equipment removes mastics and thin-set mortars, creating a final floor surface preparation and/or polishing of the concrete surface.
Floor Scraping & Removal
Removes carpet, VCT, vinyl, ceramics, hardwoods, elastomerics, epoxies, decorative coatings, roofing materials, sport courts and many other surface coverings.
Sandblasting
Prepares a surface for better adhesion of a new layer of concrete or paint, reveals aggregate for decorative reasons, etches a design or thoroughly cleans the surface.
Shotblasting
Proper surface preparation whenever new flooring has to bond to concrete or other substrates. It produces very little airborne dust, which matters in enclosed, occupied facilities.
Projects
Surface Preparation on recent jobs
Failed floor replacement, NW salsa facility
An epoxy floor installed by another contractor delaminated almost immediately. CRI removed it and installed BASF Ucrete BC6 in three phases while the plant kept producing.

Explorer Middle School locker rooms
Old epoxy quartz removed and 3,050+ square feet of slip- and chemical-resistant seamless flooring installed while swim practice continued next door.
VA Puget Sound Health Care, operating rooms
New seamless floors in operating and X-ray rooms, installed one room at a time with low-VOC products so the rest of the surgical wing kept operating.
